PRODUCT OVERVIEW
Cooperheat Rope Heaters are flexible resistance heating elements designed for reliable preheating of pipe welds and cylindrical components in industrial welding applications. Constructed with a nickel-chromium heating core and protective braided outer covering, these heaters provide uniform heat distribution along their surface, eliminating hot spots and ensuring consistent preheat temperatures. With flexible installation and multiple length options, rope heaters are ideal for pipe diameters ranging from 152 mm to 508 mm.
Product description
Cooperheat Rope Heaters are engineered to deliver efficient and controlled preheating for welding and fabrication processes involving pipes and cylindrical structures. Designed with flexibility and durability in mind, these heaters can be easily wound around pipe surfaces to provide localized heating before welding, helping to improve weld quality and reduce the risk of thermal cracking.
The heating element core is made from stranded nickel-chromium resistance wire, which provides excellent heat generation and durability under high-temperature conditions. This core is insulated with porcelain beads to ensure electrical insulation and consistent thermal performance. The entire assembly is protected by a closely braided nickel-chrome wire outer covering, which distributes heat evenly along the heater’s surface, eliminating hot spots and ensuring uniform heating.
Cooperheat rope heaters are supplied with 200 mm cold tails at either end for convenient electrical connections and flexible positioning. With an approximate diameter of 13 mm, they are compact yet powerful enough to deliver reliable heating in demanding industrial environments.
These heaters are specifically designed to be wrapped around pipes with diameters ranging from 152 mm to 508 mm. When positioned on either side of a weld joint, rope heaters provide effective and controlled preheating, improving weld integrity and meeting industry heat treatment requirements.
Widely used in industries such as oil & gas, petrochemical, power generation, and heavy engineering, Cooperheat Rope Heaters provide a practical and dependable solution for localized preheating of pipe welds and fabrication components.
